Description

July 9, 1940. G. w. BRUDERICK SIGNAL SYSTEM FOR MOTOR-DRIVEN VEHICLES Filed Nov. '7, 1958 Patented July 9, 1940 UNITED STATES PATENT orricr.
SIGNAL SYSTEM FOR MOTOR-DRIVEN VEHICLES ation manually prior to the turning of the steering wheel, and which are automatically returned to their inoperative positions when the steering wheel is moved back to its middle or straightaway position.
Another object of my invention is to provide supplementary lights which are positioned in or near the front of the vehicle on either side and operated simultaneously with the right and left hand turn signals, whereby a light is projected lateraly so as to illuminate the road in the direction in which it is intended to turn and also to be visible to drivers approaching from that direction.
A further object of my said invention is to provide an improved switch for signal systems of the character recited and which is simple in construction, reliable in operation, and which can be easily and quickly adjusted to suit the convenience of the diiierent operators.
With these and other objects in view, I will now describe a preferred embodiment of my invention, reference being had to the accompanying drawing, in which Figure 1 is a diagrammatical side elevation showing locations of. the various elements of the system.
Figure 2 is a diagrammatical front elevation of the same.
Figure 3 is a vertical sectional elevation showing one construction of my improved switch in detail.
Figure 4 is a vertical sectional view taken on line 4--4 of Figure 3.
Figure 5 is a horizontal sectional view taken on line 5-5 of Figure 3 showing the manual operating means.
Figure 6 is a similar section take on line 6-6 of Figure 3 showing the movable switch arm.
Figure 7 is a similar view taken on line I-I of Figure 3 showing the arrangement of the fixed contact members of the switch.
Figure 8 is a front elevation showing one construction of the signal lamp to be used with my system.
Like characters designate corresponding parts throughout the several views.
Referring more particularly to Figures 1 and 2 of the drawing, R and L designate the right and left hand signals, respectively, which are in the present example located in front and rear inside the vehicle so as to be visible through the windshield and the rear window, respectively, as will be understood.
R and L indicate supplementary turning lights which are here shown as being incorporated with the regular headlights H but which may be constructed as separate units and located upon the fenders or in any desired position. W is the steering wheel mounted upon. the usual pillar W while S indicates the operating switch which is so mounted upon the said pillar as to be adjustable to suit the convenience of the operator, as above stated.
Referring now to Figures 3 to 7, inclusive, I is a bracket formed from sheet steel or other suitable material having concave portions I adapted to fit against the uppersurface of the pillar W and secured in position by a U-shaped clamp member 2 and screws 2'. Rotatably mounted upon the bracket I is a shaft 3, the lower end of which is loosely supported in a bearing 4' in the fiber block 4 secured to the bracket, while the upper end is so arranged as to be slidably and rotatably supported between upwardly projecting ears I formed integral with the upper portion of the bracket. Upon the upper extremity of the shaft 3 is mounted a wheel 5, of rubber or other resilient material which is bored to fit the reduced portion 3 of the shaft and is clamped tightly in position between metal washers 6 and by the nut I as shown more clearly in Figure 3. Intermediate the upper and lower horizontal members of the bracket I is a sleeve 8 which is maintained in frictional driving relation with the shaft 3 by means of a bolt 8' which serves to draw the projecting ears or lugs 8" together so as to produce the desired amount of friction.
Pivotally secured to the upper member of the 3 bracket I as by a screw 9 and nuts 9 is the manually operated lever 9, and upon the upper face of this lever is mounted a cam I0 which is maintained in co-operative relation with the cam roller II, upon the sleeve 8, by means of the helical tension spring I2, one end of which engages a reduced portion 3" in the shaft 3 while the other end is formed with a hooked portion adapted to engage the hole 9 in the screw 9.
Upon the lever 9 is also a segmental gear I2, the
teeth of which engage a similar gear I3 formed integral with or secured to the sleeve 8, the arrangement being such that when the lever 9 is rotated in one direction or the otherabout its pivotal screw 9' the sleeve 8 will also be rotated due to the action of the gears I2, I3, and the upper end of the shaft 3 will thus be moved, against the action of the spring I2, in a direction away from the lever 9 through the action of the cam I ll upon the roller II. ment of the lever 9 will bring the beveled periphery of the wheel 5 into frictional engagement with the hub W" of the steering wheel, so that movement of the latter in one direction or the other will cause rotation of the shaft 3.
Such move- Pivotally mounted upon a lug 8' by means of the screw I4 is a switch arm H, of fiber or other insulating material which carries upon its lower face a contact member l4" secured in position by means of a screw H' which threadedly engages it. Radially disposed upon the upper surface of the fiber block 4 are the contact members l5, l5 and I5", each secured in position by-screws l6 which project directly below the underside of the block and are provided with nuts l6 between which are clamped the connecting wires I! in the manner well known in the art. The switch arm I 4 is yieldingly pressed downwards by means of the mouse trap type spring l4"", secured in position by the screw l4 so as to maintain the contact member H" in frictional engagement with one or more of the contact members l5, l5, l5", following the conventional switch construction.
The contact member I5 is connected to the bulbs of the left hand signal and turning lights L and L and the member l5" to those of the right hand lights R and R, while the center contact member I 5' is connected to the source of current supply as by the ammeter terminal. Switch means may be inserted in the circuits for cutting out the turning lights R, L during the daytime. All of these connections are so common in the art that no further explanation is deemed necessary.
A housing S, attached to the frame I by screws as shown at S", serves to protect the mechanism of the switch from dirt and injury. The right and left hand signals, as shown in Figures 2 and 8, consist essentially of a housing H having arrow-shaped perforations R and L each having a separate light bulb behind it in the conventional manner. Glass panes of any desired color, such as amber, cover the perforations.
The operation of the switch mechanism is as follows:
Assuming that the steering wheel is in the middle or straight-away position and the operator intends to make a right hand turn, he first moves the lever 9 in the direction indicated by the arrow R" in Figure 5, which causes the sleeve 8 and with it the frictionally driven shaft 3 to rotate in the opposite direction as indicated by the arrow R' until the segmental gears l2, l3 arrive at their locked positions, at which time the contact member [4" of the switch arm I4 is in a position to bridge the contact members l5, l5" and thus energizing the bulbs of the lights R and R. v
This movement of the lever 9 also, through the action of the cam upon the roller ll, causes the wheel to come into frictional contact with the hub W" of the steering wheel, so that when the latter is operated, at the proper time, to make the right hand turn, the wheel 5 and the shaft 3 are rotated as indicated in the direction of the arrow R and, since the gears III, II are at the extreme limit of their movement, the shaft 3 turns within the sleeve 8, the friction between them being overcome by the torque imparted to the wheel 5.
The lights R and R therefore continue to func-' tion until the operator turns the steering wheel back to the middle position, when the rotation of 0 the wheel 5 and shaft 3 in the opposite direction to the arrow R3 brings the contact member l4" of the switch to the central or cut-out position.
While I have herein described and shown a preferred embodiment of my invention, it will be readily understood by those skilled in the art to which the same pertains, that various changes in detail may be made to suit any particular or peculiar requirement, without departing from the spirit of my invention as defined in the appended claims.
Having thus described my said invention, what I claim and desire to secure by Letters Patent of the United States is:
1. In a signal system for automobiles, the combination, with a steering wheel having a hub, of a switch comprising a frame, a shaft rotatably and inclinably mounted upon said frame, a sleeve upon said shaft and arranged in frictional driving relation therewith, a gear fixed upon said sleeve, a second gear meshing with said firstmentioned gear pivoted to said frame and having a handle for manual rotation, a switch arm pivoted upon said sleeve and having a contact member, a plurality of fixed contact members upon said frame arranged in cooperative relation with said first-mentioned contact member, a wheel fixed to said shaft and positioned proximate to said steering wheel hub, and cam means upon said handle adapted to force said wheel into frictional engagement with said hub when said handle is moved to one side or the other of its median position.
